List<String>>：从HashMap<String，Java中的给定密钥返回随机值

import java.util.HashMap;
import java.util.List;
import java.util.Random;

public class Main {
    public static void main(String[] args) {
        HashMap<String, List<String>> hashMap = new HashMap<>();

        // 添加数据
        List<String> list = new ArrayList<>();
        list.add("Value 1");
        list.add("Value 2");
        list.add("Value 3");
        hashMap.put("Key", list);

        // 根据给定密钥获取随机值
        String key = "Key";
        List<String> values = hashMap.get(key);
        if (values != null && !values.isEmpty()) {
            int randomIndex = new Random().nextInt(values.size());
            String randomValue = values.get(randomIndex);
            System.out.println("Random Value for key \"" + key + "\": " + randomValue);
